A Houston field app is used somewhere with no signal, in daylight you cannot see a screen in, by someone wearing gloves.
App development in Houston is dominated by field and industrial applications: inspection, safety observation, asset and maintenance capture, and job data collected at sites with no connectivity. Offline-first behaviour is not a feature of these apps, it is the architecture, and everything else follows from it.
Not a dropout, a shift. Everything captured locally, photos included, queued and synced when the crew returns to coverage, with defined rules for what happens when records conflict. Design for this first or rebuild later.
Inspection and safety work is mostly photographs with annotations, timestamps and location. That is a lot of local storage and a careful upload strategy, and it is the part most quotes underestimate.
Gulf Coast daylight and work gloves are design constraints. Large targets, high contrast, minimal precision, and testing on the ruggedised device your crews carry rather than a new phone in an office.
Inspection and safety data gets read months later by somebody who was not there, and sometimes by a regulator or an insurer. Timestamps, identity, immutability and export matter as much as the capture screen does.
A field app that does not feed the maintenance, ERP or compliance system creates a second version of the truth. That integration is usually most of the work and belongs on its own quote line.
Code in your repository, apps under your accounts, and the data model documented. On an operational system this outlives whoever commissioned it, and the documentation is what keeps it maintainable.
| Factor | Why it moves the number | What to ask |
|---|---|---|
| Offline architecture | The whole design follows from it | How long offline must it survive? |
| Photographs and media | Storage, compression, upload strategy | How many images per job? |
| System integration | Usually the majority of the work | Price each connection separately |
| Compliance and audit | Immutability, identity, export | Who reads this data later? |
| Hardware | Rugged devices, sleds, tablets | Which device will you test on? |
| Rollout and training | Adoption is the risk, not the build | Who owns this in the field? |
We quote fixed scope after discovery. On a field app the offline design and the integration are the number; the screens are the cheap part.
| Ask them | A good answer sounds like | Walk away if |
|---|---|---|
| What happens with no signal for eight hours? | Full offline capture, queued sync, conflict rules | It syncs when it reconnects |
| Have you built for gloved hands in daylight? | Target sizes, contrast, and a device they tested on | It follows the platform guidelines |
| Whose developer accounts does it ship under? | Yours, from the start | Theirs, and moving it later is your problem |
| Who owns the code and the data? | You do, unconditionally, in the contract | Ownership ends when the retainer does |
Field software lives or dies offline. An agency that has not asked how long your crews go without signal has not thought about the job.
If it is office-based on reliable wifi with no camera or offline requirement, a web application avoids distribution, store review and two platform builds.
If the inspection or safety forms are being redesigned, build the form system configurable rather than freezing this month's version into code.
Field apps fail on adoption, not engineering. Without a named owner, training and a decision to switch off the paper process, it gets used for three weeks.
It depends on how long the app must survive offline, how much photographic evidence it captures and how many systems it feeds. We quote fixed scope after discovery, because those three things are the number.
That is the normal Houston requirement and it has to be designed for from the start. Everything captured locally including photographs, queued, synced on return, with defined rules for conflicting records.
It is the part most quotes underestimate. Local storage, compression, and an upload strategy that does not fail halfway through on a weak connection. Tell us how many images a job produces and we will scope it honestly.
They need to, and that shapes the build. Timestamps, identity, immutability once submitted, and an export somebody can read months later without the app. Your compliance function defines what applies and we build to it.
It usually has to, otherwise the app becomes a second version of the truth. Name the system and version early, because that integration is normally the majority of the work.
Yes, and we test on the device your crews actually carry. Large targets, high contrast for Gulf Coast daylight and minimal precision required are design constraints rather than nice extras.
Cross-platform for most field apps at roughly one build instead of two. Separate iOS app development and Android app development is justified where hardware peripherals behave differently per platform.
No. We work with Houston companies remotely on Central hours and would rather say that than imply otherwise. Not carrying local overheads is part of why our numbers differ.
Send us what you are trying to fix and we will tell you what it takes, what it costs, and whether we are the right people for it. If we are not, we will say so.
